Dr Jun Jiang a LightForm Co-Investigator from Imperial College London - Faculty of Engineering, Department of Mechanical Engineering presented "Understand and predict the superplastic forming of TA15" at The University of Manchester on Tuesday 3 December.

Jun’s talk revealed the key microstructure evolution at the superplastic forming condition captured by EBSD and embed the obtained fundamental understanding, into a unified physically-based constitutive processing modelling, to simulate the superplastic forming process.

Superplasticity has been widely used in manufacturing complex shaped titanium sheets for the aerospace and automotive applications. During the superplastic forming process, where the temperature is typically above 0.7 of the melting temperature of the alloy and strain rate is extremely slow, many mechanisms, such as dislocation generation and recovery, phase transformation, grain refinement and growth and grain boundary sliding, are involved.
